Digital asset investment products received $3.55 billion in net inflows during the week ended September 28, according to CoinShares' biweekly report published September 29. The figure marks the largest weekly inflow of 2026, breaking two weeks of flat flows across the sector.
Total assets under management in digital asset investment products rose to approximately $173 billion on the back of the inflows. Year-to-date, the sector has accumulated $8.6 billion in net inflows, the report shows.
Bitcoin products captured the bulk of last week's inflows at $2.52 billion. Ethereum products followed with $702 million, while Solana attracted $193 million and XRP drew $92.3 million. The four assets accounted for $3.54 billion of the $3.55 billion total, leaving minimal flows to other digital assets tracked by CoinShares.
CoinShares publishes biweekly flows reports tracking net inflows and outflows across regulated investment products including spot and futures exchange-traded funds, grayscale trusts and other managed vehicles. The firm's data has become a standard reference for institutional capital movements in digital assets, particularly among allocators and asset managers.
Inflows of this magnitude typically follow periods of price appreciation or reduced regulatory uncertainty. Bitcoin and Ethereum have both gained ground in recent weeks as institutional investors reassess their positioning ahead of potential policy shifts in the United States.
The $3.55 billion weekly inflow compares to the $8.6 billion accumulated year-to-date, meaning a single week captured 41 percent of all 2026 inflows to digital asset investment products. No comparable single week has approached this share at any point during the year, according to CoinShares' published records.
